Do all emergency equipment and feeders have to be located indoors, need 2 hour fire protection? If they do, can this be accomplished with a fire suppression system (building sprinklers)?
Unless NFPA 110 or some other governing body says otherwise, it is my contention that if the equipment or feeders are located in spaces that are fully sprinkled by an automatic fire supression system, I meet the requirements of NEC 700.12 (D). Am I mistaken?
